Latas Patent No. 102,340, man 'Api-n 26, 1870.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it may concern:

Be it known that I, J AMES WAYLAND, of the city, county, and State ofNew York, have invented a new and useful Improvement in Springs, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawing forming part of thisspecification, and in which- Figure 1 is a side view of a springconstructed in accordance with my improvement, and

Figure 2, a sectional view of the same, taken as iudicated by the line xa; in lig. l.

Similar letters of reference indicate corresponding parts.

My invention consists in a spring applicable as a car-spring and forother purposes, which is made up of a series of corrugated steel plates,arranged in a novel manner, to secure a large degree of elasticity andgreat lightness with strength.

Referring to the accompanying drawing- A A and A A represent two pairsof corrugated steel plates, but I do not restrict myself to any precisenumber of pairs.

Each ot' these pairs A A or A A forms a spring, although the largestbenefit is to be derived from a cluster of them, or succession ot'pairs, arranged side by side, as hereinafter described and representedin f. 2.

The corrugated plates of' each pair are arranged to occupy reversedpositions to each other, and so that their eorrugations which form innerconvex surfaces meet, as at a or a', while in 4a series of pairs of suchcorrugated plates, arranged side by side, as shown, the corrugat-ionswhich forni outer convex surfaces also meet, as at b b.

Said plates may be made up of anynumber of corrugations, according tothe required length of the 'ing on tie-rods D D, and the ends or edges cc of the plates made to enter grooves d d, formed in said bed andfollower.

Such a combination and arrangement of corrugated plates materiallydiffers from other corrugated or curved plate springs, and may he got upas cheap or cheaper, as, by the manner in which the plates brace eachother, as at a a' and b I), when pressure isap plied to the spring,there is considerable stiness imparted tothe latter, that allows ofcomparatively thin plates being used, which insures the requisiteelasticity to the spring between said bracing points or surfaces.

Thus the spring combines great tension with lightness and strength,andis devoid-.of all complicated fitting.

What is here claimed, and desired to be secured by Letters Patent, is

A spring made up of a series of corrugated plates, the coirugations ofwhich are made to abut at their convex portions against each adjacentplate, substantially as shown and described.
